Krishna,

I noticed that the tilt-subtraction with BRS-2 was being affected by the lack of a response inversion filter for the STS-2 (pair of poles at ~8.2 mHz). Therefore I tried a filter with a pair of zeros at 8.2 mHz and to prevent it running away to infinity, I put in two poles at 0.1 mHz. Unfortunately I turned it on without thinking much about it and it seems to have produced huge numbers saturating some filter banks. I have since produced a much more sensible filter with a pair of zeros at 8.2 mHz and a pair of poles at 3.5 mHz which should only increase the low-frequency numbers by a factor of ~7 instead of ~70,000!

Apologies for this issue.
